Its possible to get your cheekbones more protruded in lower parts, Its possible to reduce them in different parts. I don't know but it even might be possible to achieve lateral projection but but but...
What about your jaw and your masetter muscle? You know there are two things that are awesome about high cheekbones, I mean they make your whole face look better but two things are always the most obvious, The bones themselves protruding next to your eye and the hollowness of the cheek beneath them. If you don't have the jaw then you cant get a natural looking cheekbone by surgery, can you? I mean the surgeons can't do anything to masetter muscle connected to your cheekbone and change the shape of your lower jaw, can they?
